This invention-relates to razors and has for its object to provde a razor andfblade'of improved cutting qualities, which will be adapted for more rapid assembly and disassembly, and which will provide for individual replacement of either or both of the dual cutting edges. A,

More particularly it is anpobjectto provide a razor head comprising a clamp plate and a guard {betweenwhich thejbladeor blades are held -by a predetermined vspring pressure-thereby assuring exact positioning of the blades and a freedom fromdistortion such'as is generally caused by an unduly large amount of holding pressure when this relation or pressure is determined manually.

Another object is to provide a blade of such shape that it is capable of ilexing in its own plane and to so arrange the holding means therefor that such ilexing is possible. This entails a clamping effect such that the blade depends for its impelling effect upon abutments rather than upon a high pressure clamping by its guard and end clamp.

Another object is( to provide a construction comprising an end clamp and handle permanently secured together and to provide guards pivotally secured to the cl-amp, the guards being urged into blade clamping position by a spring acting against the guards mutually so that each receives identical pressure with the other.

Another object is to provide a pivotal connection between the handle and the head whereby the head may be swung to a position paralleling the handle. It may then be inserted into a narrower case.

A further object is to provide a handle having a drawer or magazine for the blades.

Other objects and advantages will become hereinafter more fully apparent as reference is had to the accompanying drawings wherein my invention is illustrated and in which Figure 1 is a front View of my improved razor with the handle partially broken away;

Fig. 2 is an endwise plan view of the razor;

Fig. 3 is a side elevation of the razor of Figure 1;

, Fig. 1'2 shows the razor in position for insertion into a casing.; and j ,g Fig. 13 shows a modied handle. 1

More particularly I indicates a razorflhandle equipped with a drawer 2 for retaining blades3, pending use. VPivotally secured to the handle I is an end clamp l having brackets 5 at eachend thereof andra central depending member or post integral therewith. The handle and end'clamp may be `secured together as `illustrated without "the use'ofy a bolt,f thereby making a neat ijoint. Throught'he post 5. and brackets 5, a'pin] is inserted to constitute a hinge 'pin for individually pivoted guards 3 which are notched or serrated at 9, as is conventional practice. One or more springs I0 are secured to the pin 1 with its ends pressing upwardly to urge each of the guards 8 towards the clamp plate. With the spring IU of coil type and wrapped loosely around the pin 1 it is evident that the guards 8 will each be subjected to identical pressures. l

In order to open the guards 8 with respect to the end clamp 4, I provide thumb rests I I. When a guard is depressed into the position shown in Figs. 10 and 11, the blade 3 may be placed in position and upon release of the thumb rest the blade is then held with the pressure dictated byk the spring I0. 'g

The blade 3 is preferably made exactly as shown with the Width at the outer edges being suicient to expose its cutting edge into cutting position and its rear edges I2 abutting against the brackets 5. The ears I3 project outwardly to constitute both apart of the abutment means and as a means for grasping the blade for insertion and removal. Between the endgportions I3 the rear edge is decidedly curved so that the midportion is of very little greater width than the tapered cutting edge. This will give a flexibility in the plane of the blade because of this shape and because the blade is held by a predetermined spring pressure. In other words the clamping effect is only suicient to hold the blade in position but not enough to interfere with flexibility of the blade in its plane because the force exerted by the hand of a user is transmitted through the brackets 5 to the rear edges I2 rather than through the body of the blade. This, of course, is true for both blades 3 as the construction and arrangement of the two guards 8, each of which has a separate blade 3, is identical and the shape of both blades 3 is identical. By this construction the blade may be uniformly tempered which is not possible with conventional blades because with a wide blade if the. center is tempered similarly to the cutting edge it will fracture under clamping pressures. This blade is therefore considerably cheaper to manufacture while retaining highest quality.

When the razor is not in use, the head comprising the end clamp 4 and both guards may be tilted to the position illustrated in Fig. 12 for insertion into a casing I4. The blades do not need to be removed.

As shown in Fig. 13, the drawer 2 may be omitted and the extra blades stored in the hollow handle which is provided with an end closure cap 15.

What I claim is:-

1. A razor comprising a handle, a blade seat member extending transversely of said handle opposite an end thereof, dual blade guards pivotally mounted upon said member to swing toward and from the seat side thereof, and spring means common to both of said guards for urging 44'said guards toward said member with equalzed-pres-V.

Sures to clamp a blade between said member and guards.

2. A razor comprising a handle, a blade seat member pivotally secured to said handle, a Ablade on each side of said handle each in pivotal relation with said member and said handle, and spring means for urging said guards towards said member.

3. A razor comprising a handle, an end blade seat member pivotally secured to one end of said handle to swing transversely to said end, dual blade guardsv pivotally mounted between said handle'and member, and lspring means for urging member for the seating thereagainst of a. blade, said end member having a hinge pin bracket depending from each end thereof, a hinge pin carried by said brackets, dual blade guards piv-V `otally secured to said hinge pin to swing thereon at opposite sides thereof toward and from said member, and means for urging said guards toward said end member to clamp the blade therebetween.

6. In arazor,v an end clamp having brackets dependingV from the ends thereof and a post depending from'its center, a hinge pin extending through said -post and said brackets, a handle pivotally secured to said'post below said hinge pin,V a blade guard on each side `of said post each mounted on said hinge pin,- and a coil spring wound around said hinge pin and having its ends in pressure contact with each of said blade guards whereby said guardsare urged toward said end clamp.
